T0 at whom it may concern.- v

Be it known that'I, WILLIAM RABICH, a, citizen ofthe United States, residing at St. Louis, in the State of Missouri, (whose postoffice address is 3010 Hickory street,) have invented certain new and useful Improvements in Pill-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will en-' able others skilled in the art to which it appe'rtains to make and use the same, reference beinghad to the 'accompanyingdravw. ings, and to the figures of reference marked thereon, whichform apart of thisspecification.-' This invention relates to' improvements in a compressor-die for pill-machin es; and itconsists in the novel arrangement, construction, and combination of parts, as willbe more fully hereinafter described, and set forth-in theclaims.

The object of this inventionis to construct a die to be adjustable, and itsplungerar-l ranged to spread or part on its upward motion, so as to release the pill in case the same should be in any way connected'thereon; Figure 1 is a side elevation of the plunger and spreader attachment, the die shown in section, the parts being detached from the machine. Fig. 2 is asimilar View as Fig 1, showing the plunger-in pressing operation. Fig. 3 is a vertical sectional view of a modified form of die where an elongated shaped pill is formed. Fig.4 is avertical section showing the hinged plunger in its open position after the compression of'the pill.

In the construction of the device as shown I provide adie or casing 1, consisting of a cylindrical bod y, provided with a threaded bore or receiving or pressure chamber 2 and a forming part 3. Inthe bore 2 is an adjustable nut or die-plunger 4, having a projection 5 extending into the part 3 and its face provided with the die for forming thepill. Through the nut is formed a bore 6,the purpose of which is to allow the passage of the plunger 7 to raisetherein and free the pill from the lower half of the die and'pass it to the top of the part3, removing it therefrom. This action is brought about whenthe pill is from'the die.

with the adjustable portion, operates a plunger-die 8, consisting'of two parts, one stationary and the other part 9 hinged. The purpose of this is to providea means whereby the pill can be readily released from the end I of the plunger in cases where the same may This feature is accomplished stick thereto. 7 by. the dog 10, hingedly carried by the stationary portion of the plunger. [On the upward movement of the plunger the dog-10 comes in contact with the dog on projection 11, formed on the bracket-l2,-wl1ich is carriedby the machine, and spreads the portion 9 of the plungerapart'from the stationary V member'and releasing the'pill.

As :shown in the modification, I provid and construct a die with an additional nipple 13, held upwardlyby aspring and provided with an elongated opening 14 for forming pills of such shape. I

Having fully described my invention, what I claim is- V 1. Acompressor-dieforpillrnachines,com-

' prising a casing, a die-plunger adjustably 'mounted in the casing, a spreading plunger .and'means for operatingthe same, -substan tially' as specified 2. A compressor-die for pillhnachines, cornprising va casing, a die plunger ad ustably mounted in the casing, an upwardly-movlng plunger operating throughithecasing, and a spreading plunger for compressing the material, substantially as specified.

3. Acompressor-die for pill-machines hav ing a casing provided withgareceiving-chamher, a die-plunger adj ustably mounted in the chamber, a plunger operating through the casing for releasing the pill from the chamber, a plunger for'compressing and forming thep'illinthe chamber, and means for spreading the same when released from the chamber, substantially as specified. v

4; In a deviceof'theclass described, comprising-a verticallyreciprocating plunger adapted to .spread when released from the pressure-chamber, a casing for receiving the plunger for co'nipressing the material to form the pill; and means for releasing the pill from the chamber at the upward movement of the plunger, substantially as specified.

In testimony whereof l affix mysi'gnature v in presence of two witnesse WILLIAM RABIOH Witnesses:
